Answer: D) So that Americans have a choice about getting
telemarketing calls at home
Explanation:
The question refers to an excerpt of an article titled 'Telemarketing Calls' about the National Do Not Call Registry. The topic sentence in the first paragraph states that the reason the Federal Trade Commission (FTC) held for launching the Registry was to allow Americans to choose whether or not they want to get telemarketing calls at home.
It wasn´t meant to help telemarketers update their lists of consumers, nor to ban them from calling people´s home phones.
And it´s not meant to allow people to verify the information
telemarketers have about them, but to stop any calls to be made to them.
